I just read a fascinating article on clustering architectures for databases from Kevin Closson of Polyserve (now HP). Kevin, for those of you who don’t know him, is a Golden God, at least according to StorageMojo Robin Harris, but all I can say is that he has one of the most informed and incisive views and insights on clustering, SMP, high-availability and high-performance environments in the industry. So, done with the sucking up, you can read Kevin’s bio here, and then turn your attention to his take on the shared-nothing vs. shared-everything debate. Very instructive.
I thought I would share this with the broader community because I think a lot of MySQL, SQL Server and EnterpriseDB folks who need to read this and think about this subject might otherwise miss it, simply because they may not be regular readers of Kevin’s blog.
